To all it may concern:

Be it known that I}, BENJAMIN FRANKLIN SPENCER, a citizen of'the UnitedStates, and

formerly a resident of Atlanta, in thecopnty of Fulton and State ofGeorgia, but now residing in the city of Los Angeles, State ofCalifornia, have lnvented certain new and useful Improvements inRoller-Skates, of which the following "is a specification.

My invention relates to roller skates, and the purpose of the inventionis the provision of a skate in which the'foot plate and clamping platesas well as the supporting brackets for the wheel are formed from asingle sheet of metal, thus permitting the stamping ofthe same and.thereby materially reducing the cost of manufacture.

It is also a purpose of my invention to provide a roller skate in whichthe clampmg members are positioned to effectively embrace the foot forsecurely retaining the 'skate thereupon. j

I will describe one form of roller skate embodying my invention, andwill then point out the novel features thereof in The brackets C and Cbeing bent inwardly,

claims. v

In the acompanylng drawings Figure 1 is a View showing in phantom a shoehavin skate embo ying my invention;

F1g. 2 is a view, showing in front elevation the skate shown in Fig. 1;

I Flg. 3 1s a vertical sectional view through the wheel and supportingbrackets; Fig. 4 is a view, showing the body of the skate as it isstamped from a single piece of metal and before it is bent into theforms shown in Fi land 2.

Similar reierence characters refer to similar parts in each of theseveral views.

Referring specifically. to' the drawings,

and particularly to Fig. 4, F designates a arms A and A which constitutethe toe clamp of the skate; At the rear-end of the foot plate, it isprovided with an upwardly extending extension E at the free end of whichlatter is carried a pairof forwardly applie thereto one form ofSpecification of Letters Patent.

and upwardly curved arms B and B which constitute the ankle clamp of theskate. Depending from and formed integral with the foot plate are a pairof brackets C and C which are curved inwardly, as clearly'shown in Fig.2 and are formed with o enings 15, as shown in Fig. 4 through which anaxle D extends, as clearly shown in Fig. 3; Arranged between the freeends of the brackets C and C and surrounding the axle D is a wheel W,while interposed between the hub of the wheel and the axle is a bearingsleeve S which loosely embraces the axle so that the wheel W canbe'freely rotated upon the latter. I

By reference to Figs. 1 and 2, it will be seen that the 'curvatureo'fthe arms comprising the angle clamps and toe clamp are such that theysecurely embrace the same and thereby "effectively maintain the skate inapplied position upon thefoot. As these clamps are formed lntegral withthe foot plate F, it is obvious that the employment of securing devicesof various characters as in the usual form of skate 1s ellmmated.

festly permits of the rapid making of the skate at a minimum cost ascompared to oller skates of the usual-construction. Although I haveherein shown and described only one form of roller skate embodying myinvention, it is to be understood that various, changes andmodifications may be resorted to without departing from the spirit ofthe invention and the spirit and scripe of the appended claims.

aving thus described my invention, I

claim 1. A roller skate comprising, a body formed of a single sheet ofmetal comprising, a foot plate, armsextending upwardly and, inwardly ofsaid plate adjacent the forward end.th ereof and adapted to engagethetoe portion of the foot, an extension on the rear end of the plate,ankle embracing arms on the 'free end of saidextensiomsaid armsextending forwardly, inwardly and upwardly with respect to said plate,and brackets' depending from said plate intermediate its ends, and awheel journaled in 5 said brackets.

2. A roller skate comprisin a wheel supported foot plate, a pair 0substantially rigid arms arranged on the body for clampingly engagingthe toe portion of a foot, and a second pair of substantially rigid 10arms on the body and arranged to embrace the ankle and to normallyprevent displacement of the foot from the first pair of arms.
